Arden Grove Infant and Nursery School, in Cottinghams Drive, off Reepham Road, has been left without heating, hot water or the facilities to cook hot dinners as a result of the leak, and pupils have been told not to come in.

The fault is expected to be fixed today and the school should be open again tomorrow “all being well”, says a statement on the school website.

It adds: “Sincerest apologies to our very understanding children, parents and carers.”
